[ 1913 Webster ]

☞ Proportion in the mathematical sense differs from ratio. Ratio is the relation of two quantities of the same kind, as the ratio of 5 to 10, or the ratio of 8 to 16. Proportion is the sameness or likeness of two such relations. Thus, 5 to 10 as 8 to 16; that is, 5 bears the same relation to 10 as 8 does to 16. Hence, such numbers are said to be in proportion. Proportion is expressed by symbols thus: [ 1913 Webster ] a:b::c:d, or a:b = c:d, or a/b = c/d. [ 1913 Webster ]

(b) The rule of three, in arithmetic, in which the three given terms, together with the one sought, are proportional. [ 1913 Webster ]

Continued proportion,
Inverse proportion, etc. See under Continued, Inverse, etc. --
Harmonical proportion or
Musical proportion, a relation of three or four quantities, such that the first is to the last as the difference between the first two is to the difference between the last two; thus, 2, 3, 6, are in harmonical proportion; for 2 is to 6 as 1 to 3. Thus, 24, 16, 12, 9, are harmonical, for 24:9::8:3. --
In proportion, according as; to the degree that. “In proportion as they are metaphysically true, they are morally and politically false.” Burke. [ 1913 Webster ]
